If \( x=a-b \), the maximum percentage error in the
\( \mathrm{P} \)
measurement of \( x \) will be-
W
(A) \( \left(\frac{\Delta \mathrm{a}}{\mathrm{a}}+\frac{\Delta \mathrm{b}}{\mathrm{b}}\right) \times 100 \% \)
(B) \( \left(\frac{\Delta \mathrm{a}}{\mathrm{a}}-\frac{\Delta \mathrm{b}}{\mathrm{b}}\right) \times 100 \% \)
(C) \( \left(\frac{\Delta \mathrm{a}}{\mathrm{a}-\mathrm{b}}+\frac{\Delta \mathrm{b}}{\mathrm{a}-\mathrm{b}}\right) \times 100 \% \)
(D) \( \left(\frac{\Delta \mathrm{a}}{\mathrm{a}-\mathrm{b}}-\frac{\Delta \mathrm{b}}{\mathrm{a}-\mathrm{b}}\right) \times 100 \% \)
